Be it known that I, D. S. 'HOLMAN, of 'Conncautvilla in the-'county of Crawford, and State of Pennsylvania, have invented a new vand improved Seed-Planting Machine; andxI do hereby declare that the following is aV full, clear, and exact description thereof, which will enableotlrers skilled in the art to make and use, the same, reference being had to the accompanying drawings, forming part of this specification, in which-e` i v`Figure 1 is a side sectional view of -my invention, taken in the line z, g. 2. A

Figure 2, a plan or top view of the same, w-ith a portion in section, as indicated by the line y y, iig. 3'.

Figure' 3, a .front sectional view of the same,taken in the line z z, iig. 1.

Figure 4, an enlarged detached side view of one of the wheels by which the-seed slides are operated.

Similar letters of reference indicate like parts.

This invention relates to a new and improved machine *for planting seed, and it consists in a novel seed dropping device with means for regulating the discharge of the seed, and also in animprcved means for opening' the furrows and covering the seed after being dropped therein, as hereinafter. fully-shown and'described.

'A represents a platform or framing having thills, latthehed, and bearings, a a, an axle, C, being fitted in the latter so as to turn freely. On the axle C two wheels, D-D, are placed loosely, one wheel; D, having a portion or onepart, b, of a clutch attached-tio o1` formed on the inner end of itshnb, the other part, b', of the clutch being placed on the axle'so as to be capable of sliding thereon, but at all times turning with it, the'l part 4b being moved or adjustedby a lever, Ac,'within convenient reach of the driver on seat E, F F are two secdboxes,'whioh are secured to a bar at the rear of .the platform A, the endsY ofsaid bar projecting beyond the sides of the platform so that the boxes F F will be at the sides off-the same. Each seed-box, F,is provided with a pendent turbe, G, in the upper part of which, at the bottoms of the lh'oppers, horizontalseed-slides, H H-, are placed and allowed to work freely. These slides have Aeachn spring, d, bearing against lits outer end, and said springs have a tendency' to keep the slides HH shoved inward, so as to prevent the dischargeof sedfrom the seedboxes. This will bc fully understood by referring to iig. 1. Ou the-axle() there are keyed two wheels, I I, one at each side of the platform A, between it and the seed-boxes. These wheels, I,- may be termed double ones, as each has a circular proje'ction, e, at one side.v The peripheries of the wheels I vhave pins, fdriven radially into them at suitable and equal'distanees apart, and the peripheries ofthe projections e have similar pins, g, driven into them. These pins, fg, asthe axle and wheels'l'rotatqcome in contact with arms E on the slides H H', and force said slides outward to admit of the escape of lseed from the hoppers, the pins g in the projectionse being in line with'the centres of the spaces between the pins f, so that the slides will be actuated alternately, one being closed .while the other is open. In the upper part of cach tube, Gr, between thc two slides H H', there is fitted aslideh v J, which is secured in position by a screw, 7L. lhcse slides, J, by being adjusted further in or out, contract or' enlarge the space in the tubesl Gr between the slides H Hrand ift will therefore be seen thatvby .adjusting these slides J, a greater or less quantity of seed may be discharged ttt each dropping, as desired, and that by shoving the slides J fully inward,'the discharge of seed is entirely prevented. When the upper slides, H, are forced outx ward by the pins f, the lower slides -H5 are'prcssed inward'by'their springs d andhcld the seed, and when the upper slides H :1re forced -backiby -the springs-d, thc lower slidcs-IInrc forced outward by the pins of the projections e, and thc seed is discharged, the upper slides H'scrving ascut-oifs, and the space between the slides H H serving as seed measures, the capa-city of which may, as previously stated, be .regulatcdby adjusting the slides J. To the lower "en-d of each lube G thcrc is secured a iicxiblc tube, K, both of which tubes are inserted in metallic tubes, L, having their lowerl ends of such a shape thiit they may serve as furrow openers. These 1 tubes L arc secured to thc rear ends of `feds, M, thc front ends of which are connected by joints, 'h",I to the l front end of the platform A. The rods M have rods, N, attached, which ex,tend back of the tubes L, and have cov bring shares, Q, secured to them. Each rod, N, is connected by a wire, to cranks, at the ends of'a sf aft, P, which has its bearings at the rear of the platform, said shaft being'eonnected by an arm, j, and link,

k. wfn a lever, Q, within convenient' reaehoftthe driverj on s eat E,Aand this lever is secured at any desired point witlvn lthe scope of its movement by a ra-ck, R, secured to the upper part of one of the `seed-boxes. By adjustJ 'P ing the lever-Q the fuLl-ov openers maybe made to penetrate into the earth at a greater or less depth,as desired,

:8nd .may be sustained above thefsurace of the earth when required. The seed-dropping appaiatn's may be ren-f dered inoperative at any time by disconnecting the wheel D fromthe axle G, through themedium' `of' tle clutch,l and in case it is desiied to plant only one row of seed at once, the sldeJ of one seed-boxis slioved fnlly inwardy to prevent the discharge of seed from it.' p

Having thus described my invention, whatI claim as new, and ueslre'to secure ,by Letters Patent, iss-- 1. The two seed-slides EH', placed one abo've' the other at the lippenv part of the tubes G, and'lxaving springs, d, bearing against them, in combinntionwitli thewheels L and projections er, having1pins, f .i n their peripheries, all arranged tooperate snbstantially in the manneras andfor the purpose setforth.

,2. The regulating slides J, in combination with tll'e seed-slids H Hf, arranged substantially as and for tbe 'purpose specied'. I A i l Y 3. The combination of the metallic tubes L, and covering shares 0, all arranged and oppliedso as to 'be capable of operating and being adjusted, substantially' ns shown and descifibed.
